Current HDD compatible with ReadyNAS Duo
Hello,
I have an old but still functioning ReadyNAS Duo V1 and i would like to buy new HDD. However none of the old HDD that were on the compatibility list are available thes days. Before i make the purchase, I wanted to check with the community to see if the Seagate IronwWolf 4TB Sata NAS HDD will be OK?
Thanks for your help.

No. You'd double the storage, but give up RAID redundancy. So it's definitely not as reliable.

I can sketch it out. But to be clear - you can get 4 TB of total storage, but the drives can only be 2 TB each.
First you'll need to install RAIDar 4.3.8 on a PC. RAIDar 6.x won't work for this. https://kb.netgear.com/20684/ReadyNAS-Downloads
Then you do a factory reset of the NAS with only one disk in place. After you do the reset, you have a short window of time (about 5 minutes) to use RAIDar to change the NAS from XRAID to FlexRAID. When you do that, select RAID-0.
After that, you can proceed to set up the NAS - including putting creating some shares on the C volume. Then hot-insert the second disk, and use the NAS web ui to create a second "D" volume with the second disk. Create the rest of the shares on the D volume.
Finally, restore the files from backup.
You do need to manage free space on both volumes, so it is helpful if you write down the amount of space each share needs before you begin, and then create the shares so that both volumes have good free space.

Welcome to the Community!
If it's a Duo V1 it's not going to be compatible since Duo V1s can only handle upto 2TB drives for each bay.but if it's a Duo V2 it just might work since 4TB drives are okay with it.
You can check if you have the v1 or v2 by looking at the FW used. v1 will have Raidiator 4.x while V2s will have OS5.

As Marc says, a v1 (which runs 4.1.x firmware) is limited to 2 TB. You can replace the disks with WD20EFRX or 2 TB Seagate Ironwolfs. I recommend avoiding the WD20EFAX as they are SMR drives.
If you need 4 TB of storage, you can set up the NAS in FlexRAID and create two volumes (one per disk). Using RAID-0 to create a single volume is also possible, but that is more fragile than jbod, so I don't recommend it. With one volume, you'll lose all the data when either disk fails.
Hi Stephen,
Thanks for your good advice. I don't have the NAS in front of me but could you explain me how to get the FlexRaid created with 2 drives of 4 TB? Will it be as reliable as RAID1?
Really appreciate your help on this.
I really thank the community who replied quickly. I should have written here earlier than that. I'm grateful.
